D3-GHR Polymorphism and Turner Syndrome

December 2, 2015 updated by: Gerhard Binder, University Hospital Tuebingen

D3-Growth Hormone Receptor Polymorphism and Total Effect of Recombinant Human Growth Hormone on Growth in Girls With Turner Syndrome

The protein polymorphism of the growth hormone receptor characterized by the genomic deletion of exon 3 has been linked to the magnitude of the first-year-growth response to growth hormone (GH) in girls with Turner syndrome.

Objective: to study the long-term effect of GH therapy in Turner syndrome in correlation to this GHR polymorphism in a mainly retrospective design (chart-review).
